Wynand Posted September 17, 2014 Share Posted September 17, 2014 I'm brand new here and live in South Africa. I bought a GH4 from a dealer that had to import the camera as Panasonic seems not to supply it to South Africa currently. So, I'm rather alone in trying to sort things out. After doing about 300 short movie clips with it, I kind of know the camera by now. My problem comes after shooting a clip. I use Premiere CS6 and Vegas 13 to do my rendering and all the clips are shot in CinelikeD CK4 24p profile. When I import the clip from the camera's Sandisk 280Mbps U3 Ultra Fast Card into Premiere, I render the clip before exporting in 1080p. The rendered product does not play back smoothly. It has numerous "judders / jitters) and makes the footages useless. We use the PAL system here and I have wondered if the problem could be a sync issue between the 24p and the PAL system (which is 25p). I use a i5 PC with Windows Professional 64bit, 8Gb Ram and a 7200 rpm drive (2Tb). I also installed a quality 4Gb Asus graphics card. Last week I took my footage to a media house working with top end Apple PCs, asked them to render the file and got about the same "poor" result. I must say they said it was the first time they worked with 4K. What am I doing wrong? I'm by now at then of the rope and frustrated. Any suggestions / help will be highly appreciated.

Sebastien Farges Posted September 17, 2014 Share Posted September 17, 2014 the problem is in your timeline ? Did you switch on 1/2 quality or less on the recorder window on Premiere ? Quote Link to comment Share on other sites More sharing options...
Wynand Posted September 18, 2014 Author Share Posted September 18, 2014 Yes - I resized the recorder window in Premiere. When 4K content is pulled in it usally displays "zoomed" in. After resizing the recorder window till I see the full image of the first frame I normally hit the return key and render the video before exporting. (I hope I answered your question?)

Sebastien Farges Posted September 18, 2014 Share Posted September 18, 2014 I'm not talking about the size of the window... You have an option of the quality of the playback on this recorder window. If you are in full quality you can have playback problems... If you switch to lower playback quality, it should be smoother. Quote Link to comment Share on other sites More sharing options...
anti12 Posted September 19, 2014 Share Posted September 19, 2014 @Wynand - Dropping 24 FPS Movies in a 25 FPS Timeline will ad duplicate Fields to your Footage. Shoot 25p UHD if you need to export to Pal Formats. 24p is only good for Cinema, Bluray or Internet. Quote Link to comment Share on other sites More sharing options...

The problem is not the play back while in Premiere. It is the rendered file that plays with "jumps" here and there. Quote Link to comment Share on other sites More sharing options...
anti12 Posted September 20, 2014 Share Posted September 20, 2014 OK - so I will not be able to shoot CK4 24p and down convert to PAL 1080p...? No Problem if you shoot without sound.
